HVAC Services San Antonio TX | Call South Texas Air Force AC and Heating

In San Antonio's hot climate, we recommend annual maintenance for both heating and cooling systems. Regular service helps prevent breakdowns during extreme heat, improves efficiency, and extends your system's lifespan. Our maintenance includes checking refrigerant levels, cleaning components, and ensuring proper airflow.

First, check your thermostat settings and circuit breaker. If those are fine, call us immediately for emergency service. We prioritize heat-related breakdowns and can often provide same-day service. Our technicians are experienced with San Antonio's specific challenges like dirty condenser coils from local dust and pollen.

Air duct cleaning removes dust, allergens, and debris that accumulate in your ductwork over time. This improves indoor air quality, helps your system run more efficiently, and can reduce energy costs. We recommend duct cleaning every 3-5 years, or more frequently if you have pets, allergies, or recent renovations.
